Be it known that I, WILLIAM MARTIN CAI a citizen of the United States, residing at Carlton, in the county of Carlton and State of Minnesota, have invented certain new and useful Improvements in Load Retaining and Releasing Means for Vehicles; and I do here? by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to makeand use the same. My invention relates to load supporting and releasing means for vehicles, and has for its object the provision of means which may be safely operated from a secure position to release the load and which may when said vehicle is empty be conveniently reduced in height to enable said vehicle to pass under loading-machines bridging the roadway or track.

With these and other objects in view it consists, in combination with a vehicle or other load-supporting structure, of a bracket extending therefrom, a stake supporting socket journaled at its foot upon said bracket,

"means for holding said socket in a vertical position, and means governing said holding means. It also consists of certain other constr'uctions, combinations, and arrangements of parts, as will be hereinafter described and view, on an enlarged scale, of the lower porinvention.

tion of the socket forming part of my said Fig. 5 is a rear perspective view, on an enlarged scale, of the upper portion or cap of said socket. Fig. 6 is a detail vertical cross-sectional view, on an enlarged scale, of a portion of the said cap of said socket.

In the drawings, 1 isthe bolster or bunk of a logging'car, to which is secured inany suitable manner a bracket 2, preferably of the U-bolt pattern, upon which is journaled, as at 3, a stake-socket formed of two parts 4 and 5, respectively. Upon the rear face of said part4 are formed lugs 6, parallel to each other and transversely apertured near their upper ends, as at 7. Each of said lugs is also transversely apertured upon a lower plane, as at 8, from which lower aperture a slot 9, open at each end, extends rearwardly through the edge of thelug. Upon the front vertical face of said portion 4 are formed transve'rsely-apertured lugs 10. The upper inclined edges of the side walls of said part 4 are rabbeted, as at 11, to engage the oppositely-rabbeted inclined lower edges 12 of the said part 5, which latter part is superposed upon said part 4 and is provided with a transversely-apertured lug 13, formed upon its rear face and adapted to horizontally register with said lugs 6 to receive a hinge bolt 14, projected through all of said lugs 6 and 13. A transversely-apertured lug 15 is also formed upon the forward face of said part 5 from the aperture, in which a slot,

as at 15 open at both ends, penetrates the lower rearward quadrant of said lug, the aperture of which lug is adapted toregister with the apertures in said lugs 10. A suitable cylindrical locking-bolt 16. is journaled in said lugs 10 and is centrally reduced on two sides, as at 16, to adapt it to enterthrough said slot 15? into the aperture of said lug 15. A suitable weighted crank-handle l6 or other 'operating handle is provided for turning said bolt 16, whereby the greater diameter of such reduced portion may be turned across the said slot into operative position after said re duced portion is within the aperture of said lug or may be turned into the plane of said slot to enable said cap 5 to be disengaged from said bolt. The interior of said part5 is of any desirable contour in cross-section to receive a stake of any desired cross-sectional contour, which stake is represented in the drawings by a portion of a railway-track rail 17, which is retained in said part 5 and above the lower edge thereof, preferably by a bolt 17*, projected through the side walls of said or the lower portions of the lugs 6 thereon and, in releasing position, to disengage there from, may be used, and for such purpose one of said lugs 6 may, if desired, be omitted and the other placed on the vertical central line of said part 4 and may have its lower portion formed in the shape of a hook, as substantially shown in my application for Letters Patent for load-retaining mechanism, filed in the United States Patent Office on or about August 12, 1902, and numbered serially 119,405, in which event said lug 13 may be placed to one side of the central vertical line of the rear face of said part 5 and a similar lug added upon the opposite side of said vertical line, between which lugs the upper end of said lug 6 may project, said and other minor modifications being within the scope and spirit of my said invention; but I preferably employ governing means, as shown in the accompanying drawings, comprising a bracket 18, secured to said bolster and pro-. vided with wings 18 and 18 respectively, directed forwardly on opposite sides of said part 4, through which wings, in rear of said part4, is projected a cylindrical locking-bolt 19, centrally reduced on two sides, as at 19 and 19 to adapt it to enter through said slots 9 into the apertures 8 of said lug 6. Upon one end of said bolt 19 is preferably secured in any suitable manner a pipe 20, to the opposite end of which is pivoted a crank-handle 21 for rotating said bolt, whereby the greater diameter of the reduced portion of said bolt may be turned across said slots 9 into operative position after said reduced portion is within said apertures 8 of said lugs 6 or may be turned into the plane of said slots 9 to enable said part 4: to disengage from said locking-bolt. Locking means of any suitable character may be employed to secure the free end of said handle 21 to a suitable anchorage on said car to prevent accidental rotation of said bolt, such handle-locking means being well known to the art. Upon the opposite end of said bolt 19 may, if desired, be secured a pipe or link 22, secured at its opposite end to a similar locking-bolt (not shown) adapted to govern the position of another similar stake-supporting socket.

When it becomes necessary to pass an empty car equipped with my said invention beneath a log-loading machine bridging the track, said bolt 16 is given a partial rotation to bring its reduced portion into position to pass through said slot The upper portion 5 of said socket is then raised, swinging upon said hinge-bolt 1t and lowering said stake upon the platform or framework of the car, as shown in broken lines in Fig. 3. Should the car move in either direction while said stake is lowered outwardly to disembark the load, the engagement of the lower end of said part 4 with said bracket 2 is such as to permit said stakes to swing parallel with the moving car and to trail after the same.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is

1. In load retaining and releasing means, the combination with a suitable support, provided with suitable outwardly extending brackets, of a socket loosely mounted upon one of said brackets and comprising upper and lower portions, hinged together at their upper rearward edges, and normally secured together at their opposing forward edges, means for controlling the said relation of said two parts at their said forward edges, means secured to the other of said brackets and adapted, in part, to engage said socket and to normally retain said lower portion thereof in a vertical position, and adapted to be operated to release said socket from said vertical position, and a stake mounted in said socket, substantially as described.

2. In load retaining and releasing means, the combination, with'a suitable support, of a socket pivoted at its foot thereto and comprising upper aud lower portions hinged together at their rearward edges, and normally secured together at their opposing forward edges, means for controlling said connection at said forward edges, means for retaining said socket normally in vertical position, a stake mounted in said socket, and means for preventing the lateral movement of said socket when in vertical position, substantially as described.

3. In means for the purposes described the combination with a suitable support, of a stake-supporting socket loosely secured at its foot thereto and comprising a base portion and a cap portion, hinged together at their upper rearward edges and normally secured together at their forward contacting edges, the side wall of said base portion having rabbeted, inclined upper edges, adapted to engage oppositely-rabbeted inclined lower edges formed upon the side walls of said cap, looking means secured to said support and adapted, in operative position, to engage an anchorage formed upon the rear wall of said base portion near the upper end thereof, and governing means for controlling said locking means.

4. In means for the purposes described the combination with a suitable support, of a socket loosely secured at its foot thereto and comprising a base portion and a stake-supporting cap portion, hinged together at their upper rearward edges, and normally secured IIO together at their front contacting edges, an-

ameter to adapt it to enter through the slots V in said anchorages into the transverse apertures thereof,and means for rotating said bolt, substantially as described. 7

a 5. In means for the purposes described, the combination with a suitable support, of a stake-supportin g socket loosely secured at its foot to a bracket extending from said support, an anchorage formed upon the rear wall of said socket near the top thereof and comprising a transversely apertured lug or lugs, having slots, open at each end and of less vertical diameter than said apertures, penetrating through said lugs from said apertures rearwardly, a bracket extending from said support and embracing said socket on each side,
